Planning Outlook

Very unsettled through the middle of this week as a series of low pressure systems move to the north of Britain. Persistent gale force winds across the mountains, stormy at times. Heavy rain will make western areas very wet underfoot. Temperatures falling below freezing on higher mountains, particularly by Thursday, resulting in some fresh snow accumulations on tops. Heavy showers will also contain hail and a risk of thunder. Scottish mountains likely to stay sub-zero into the weekend, with some freeze and thaw cycles elsewhere. Into next week, indications favour an improvement from the south as high pressure rebuilds.
